I am constantly amazed as I read threads where someone asks the "hive" opinion of firearm X and invariable there will be 2 or 3 folks who claim that the one they bought was flawed by machine marks, poor fit, bad trigger, etc.
I have never bought a firearm that surprised me in these categories because I give them a good going over before I buy them. I can understand if you get it home and don't like the way it shoots or it is not accurate but I can't understand missing the flaws that some seem to miss before purchase.
